Mixed Reality Deck Marking Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual method of deck marking, which involves visualizing 2D technical drawings on a physical surface like a vessel's deck, is time-consuming and prone to inaccuracies, especially in the heavy shipping industry where high precision is required, leading to increased risks and reduced vessel utilization during the process.
Innovation Solution
The use of mixed reality devices, such as the Microsoft HoloLens, to project virtual footprints of loads onto the deck surface, allowing crew members or port captains to accurately and efficiently mark reference points and lines using orthographic projection, with audio-visual instructions and physical markers for correct positioning, reducing the need for manual measurement and increasing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual deck marking is used to visualize 2D technical drawings on the vessel deck, then the process can be completed with simple tools, but the time consumption increases and accuracy decreases
Solution Approach 1:
The patent replaces manual mechanical measurement and marking methods with an optical system consisting of a camera, processor, and display device. The camera captures images of the deck, the processor automatically processes these images to generate accurate 2D technical drawings, and the display device presents the final markings. This substitution of mechanical manual work with automated optical-electronic processing significantly improves both accuracy and reduces time consumption.
2Reliability
If manual visualization of 2D technical drawings is performed by port captains, then no specialized equipment is needed, but the risk of incorrect marking increases
Solution Approach 1:
The system performs self-service by automatically capturing deck images, processing them to generate technical drawings, and producing accurate markings without requiring manual intervention from port captains. The automated image processing and calculation algorithms eliminate human error in measurement and visualization, significantly improving reliability while the integrated nature of the system keeps complexity manageable.
3Productivity
If traditional manual deck marking is used, then the process can proceed without technical equipment, but vessel utilization is reduced during marking
Solution Approach 1:
By replacing manual deck marking with an automated optical system, the time required for deck marking is dramatically reduced. The camera and processor work continuously and quickly to generate accurate markings, allowing the vessel to return to commercial use much faster. This improves vessel utilization (productivity) while the system remains relatively simple to implement, requiring only a camera, processor, and display device.
